H. A. W. WQOD SHEET THROW-OUT MECHANISM Original Filed Nov. 5, 1917 .the position shown in full lines. however, the handle 26 is raised against the and holds the shaft and its several arms in When,

the roller 1t to enter the depressions 11 inl the disc l0.

llt will be understood that the trip toe 33 is adapted to move 'ust to such position and is just long enoug to hold the roller 14 practically in contact with the circular surface of the disc and prevent it entering the depressions. Therefore, when the trip handle is in the position shown in Fig. 2 this throw-out mechanism is out of operation.

twill be ohserved that there is a series of stationary guides 34: or stops supported by a bar 35 on the frame and projecting into a position to receive a sheet or folded product from the switches l18.

Tn operation, when it is desired to'throwy out a folded. product for inspection the handle 26 is lifted against the stop pin 38, thus moving the trip toe 33 from. under the lock lever 36 into the dotted line position in l? ig. 2. The circular part of the disc l0 receives the pressure from the roller 14 due to the s ring 23 and holds the roller in siibstantially the position in which it is when the throw-out mechanism is at. rest, but when a depression ll comes into registration withl the roller 14: the roller will now be free to enter it and this will cause the shaft .12 to swing slightly, taking the arm 15 with it of course, and moving the rod'21, arm 20 and shaft 19 so as to drop the switches 18 into the dotted line, position shown in Fig. 2. This, it will be understood, is timed by the shaft 4, which is lpositively geared to the shaft ,5, and therefore the parts can be dei signed so that it will take place just in time to receive the advancing end of a folded product on the switches 18. ln this way one sheet or product is diverted directly from the rolls`2 away from the usual path and guided over the switches 18 into the station-v ary guides 34. Tf the trip handle 26 is held up against the stop 38 every tenth aper will be delivered in this way, the switches 18 immediately moving out of operative position after one' aper has been assed over thenL Ordinarily, however, on y one sheet being i requiredl for inspection, the handle 26 is held lup only until the one sheet required has been delivered and then released as there is plenty vof time in which the spring can t-urn it down before this throw-out device wiil operate ythe disc drives the arm 36 up' so t at the toe 33 can be moved under it at any time incarica b cforef the roller moves into another depresf sion.

Although T have shown only a single form of the invention and illustrated it as applied to a particular form of foldin apparatus, I am aware of the fact that modifications can be made therein by any person skilled in the art and that it can be applied to other types of folders without departing from the scope of the invention as expressed in the claims.

Therefore T do not wish tobe limited in these respects, but what T claim is:

1. In a device of the character described,

lthe combination with a folding and a delivery mechanism, of a switch connected therewith for diverting a single folded productcoming from the folding mechanism, and preventing its going to the delivery mechanisin, mechanically operated means for projecting said switch into operative position, means .for normally preventing the operation of the mechanically operated means, a hand lever, and means connected with the .hand lever for withdrawing the operating preventing means and allowing the mechanically operated means to act.

2. Tn a printing machine, the combination with a folding and a delivery mechanism, of independently controlled and constantly acting means connected therewith for diverting a folded product coming from the folding mechanism and directing it out of its normal coi'irse, and then automatically continuing the next folded productin its usual path into the 'delivery mechanism.

3. The combination with a folding and delivery mechanism, of manually controlled means operated by the delivery mechanism in synchronism therewith for periodically diverting a folded product one at a time from a series coming from the folding mechanism and preventing its going to the delivery mechanism.

.4. The combination with a folding device, of a switching device loc-ated normally out of the path of said folded products, and yielding means for projecting said switching device intol the path of the folded roducts in timeto receive one'as it leaves t e folding device and then automatically retracting it.

5. The combination with a folding device .adaptedto deliver its product in a certain products, `a shaft, and means operated hy..VV
